Hey! It's another GDTV21 jammer. Glad to see you're still making games!
Your core loop is straightforward and appealing. Your audio clips are goofy and the ghost sprites are the perfect amount of odd. Unfortunately, it sort of missed the mark for me. I liked the idea of growing stronger, but playing at those early power levels didn't feel good either. If you want the player to get stronger over time, you have to make sure the early parts still are fun, too. I played 4 deaths before using the "TLDG" button, and despite multiple jump upgrades, I still couldn't reach anything beside the upper level. Making sure all parts of your game are fun is important - players don't want to have to "put in the work" to get to the fun part later.
That being said, I still played all the way through in beast mode. I found out I could keep spending and leveling up even after it said "max upgrade". I got my health upwards of 800k. My fire rate was so fast that I think the bullets were colliding with themselves and destroying immediately. My jump shot me straight through to the top in the blink of an eye. I was a ghost killing god. The red ghost stood no chance. It was oddly satisfying lol.
Congrats on finishing another game. Keep making games and keep improving!
